Jayson Tatum has been in the NBA for three seasons now. But to some, he’s still only 19 years old.

Obviously, the Boston Celtics forward is 22. But his rookie year (when he was 19) was one fans always will remember. They loved pointing out just how young Tatum was whenever he’d go off in a game — which was quite often.

The “he’s only 19” jokes carried into the following season, and the season after that. It soon became something he couldn’t escape, as Celtics Twitter still loves tweeting out the years-old joke when he completes a highlight-reel play.

Tatum never really spoke on the matter until Thursday when he held an “ask me anything” on Twitter. One Twitter user asked “What’s it like to be 19 for this long?”
